how to edit the configuration file of boost in slave using buildbot ShellCommand?

Question

So I am trying to build and test boost in the remote slave( mac ). I want to edit tools/build/v2/user-config.jam file so that I could use the toolset=clang.

How can I add

//in user-config.jam
// toolset will use clang

using clang
   : ...etc

in the user-config.jam file?

Answer 1

It turns out that unix has a nice little command called

echo  

so what I can do is use this command to edit that file.

ShellCommand(
    name = "append config instruction"
    command=['echo','I am adding this configuration cause it was missing','>','~/user-config.jam']
 )

This command will add that line in the configuration file.

if you want to make it look like "I am adding this configuration cause it was missing" I meant to add "" then

echo "\"xyz\"" > text.txt
